To aZZ whom it may 00mm.-

Be it known; that'I, F RANK L. NORTON, a citi zen of'the United States,residing'at St. Louis, State of Missouri, have invented ce'r} tai'n newand riseful lmprovements in Concrete Mixing and Distributing Apparatus,of which the following is a specification, reference'being had thereinto the accompanyinv drawing. p 7

My invention relates .to improvements. in concrete mixing anddistributing apparatus and has for its object to provide a mechanismwhereby concrete is mixed and elevated in a' rotating receptacle anddischarged therefrom at the highest point towhich the receptacle islifted, intoa distributing trough.

In the drawings I k v F igl 1 is a side elevation of an -apparatusembodying my invention.

Fig. diagrammatic view of the drum or receptacle employed thereinshowing its lid or closure in opened position.

Fig. 3 is a like view of the same with the lid in closed position.

Fig. 4 is a like view of the same illustrating the closure open and inposition to discharge its contents.

Fig. 5 is a longitudinal vertical View of a fragment of one end of oneof the mixing drums employed in the machine of my invention.

Fig. 6 is a top plan view of one of said drums.

Fig. 7 is an end View of the cover of one of said drums.

Fig. 8 is a perspective view of one of the pins wherewith thecover-latch engages.

Fig. 9 is a top plan view illustrating the baflies employed in saiddrums.

I employ a frame comprising standards 6 and 7, joined at their tops bythe cross-arm 8 andconnected by the brace 9 (carrying the distributingtrough 10) and the beam 11, on which the arm 12 is mounted by meansofthe hinge 13.

I employ two drums, 14 and 15, on the opposite sides of the frame, eachhaving a sprocket-wheel 16 engaging with the chain 17 one end of whichchain 17 is secured to the standard 6 at the point indicated as 18, theother end at 19 to the standard 7. The drums 14 and 15 are so disposed,and the chain 17 is so carried by the sprocket wheels 20 and 21 mountedon the upper part of the frame that the drum 15 is at the bottom of it'spathlofftravel when the 14Qis at its topms'tppsitm as' shown in, Fig. 1.I

Each; of said drums mend has a cover 2 provided at' east; an with stage}.23 which is i'seatedjin the recess 24 (formed be; tween the" circularhead "25 and interior head 26 of the drum as shown in 5) when the cover22"is in the'clos'ed position indicated in ins 27 i are mounted in thedrurn-ends, and project within, the, drum, and are formed as shownlin-8, having'a rounded head 28 beneath which both sides are cut away toform the grooves 29. pon the up per face of'the" cover 22 aredatches30%30 having circular; perturesjai whi h admit the heads 28: of the pins27, slots 32 extending rea-fwardly from said apertures and bemg.dimens16ned to engage the grooves 1 that (adverse-by a clamp 33,- whichis avlocking bar 39 whose indentations 40 and 41' engage with a pin 42when the cover 22 is in fully or partly opened position as shown inFigs. 2 and 4; the bar 39 hanging idle when the cover 22 is in closed psition, as shown in Fig. 3.

In the interior of each drum I provide one radially-disposed partition43 extending from end to end of the drums interior and from its axis toits bottom. Transversely above said partition 43 the battles 44 armounted, as shown in Figs. 2 and 9. V

The cover 22 has a handle 55 which is so located that it will be graspedtogether with the cross-bar 35 by the hand of the operator when thecover 22 is in unlatched position and it is desired to 0 en it.

This opening is e ected when the drum 15 is in its lowest position, asshown in Fig. 1. The drum 15 is then supplied with a charge of concrete,and the cover 22 closed and latched by hand. The crank 45 is thenoperated to raise the drum-15 and lower the drum 14. When the drum 15has ascended to a point in alinement with the end of the unlocking bar46, the roller 47 mounted on said bar 46 will contact with the guide 48and the continued rotation of the drum 15 will bring the bar 46 intocontact with the lever 36, forcingsaid lever outwardly to unlatch thecover 22 which will, upon the further revolution of said drum,.drop bygravityinto the opened and discharging position illustrated in Fig. 4and at the lefthand side of Fig. 1, in which position its contents willbe liberated, and discharged by their own weight into thetrough 10.

A corresponding unlocking bar .48 with a roller 49 serves-to unlock thedrum 14 as shown in Fig. 1. A stop 50 serves to limit the downwardmovement of the unlocking bars 46 and 48. In thedescending course of thedrums 14 and15, when empty, the bars 46 and 48 serve to again latchtheir covers; p p 5 As shown in the drawings the lid or cover 22 isprovided with a tactically water-tight hinge construction. he lid 22has'its rear edge convexed as indicated by 51, to register with alongitudinal flange or corrugation 52 inthe edge of the outer wall 53ofthe drum. The hinge 54 bein secured to the outer face of the lid 22, the%ange 52 serves, when the lid 22 is in the opened osition' shown in Fig.2, to prevent any lea age of the drum content at the hinge-line, whilesaid drumeontent is being discharged.

The baffles 44 are arranged parallel with 2 each other and at an angleto the partition 43, and as shown in Fig. 9 extend entirely across theinterior of the drum.

Having thus described my invention, what I claim and desire to havesecured to me by the grant of Letters Patent is- 1. In a device of theclass described, in combination, a vertical frame; a pair of drumsmounted upon opposite sides of said frame; means for alternately raisingand lowering each of said drums; and means comprising arms hingedlymounted on the frame and pivoted locking bars on the drums arranged tocontact with said arms for opening each drum when invraised position toliberate its contents.

2. In a device of the class described a drum having a radially disposedpartition extending from end to end of the interior of the drum and fromits axis to its bottom; and a series of baflies extending across theinterior of said drum above said partition and arranged parallelto eachother and at an angle to said partition.

In testimony whereof I hereunto aifix my signature;

FRANK L. NoRToN.
